Hi, My Cardiologist Has Been Difficult To Reach Due To

Hi,
My cardiologist has been difficult to reach due to the pandemic and my situation is a little weird. I have a lot of medical problems but I have had many tests on my heart and lungs and I don’t have any serious problems with those. I know that what I’m experiencing is not a danger to my health. It has been happening for years. But I have an Apple Watch and I’m currently having symptoms of an tight or pulling sensation in my chest and I did the ekg and I noticed that there are little blips that look like a small scribble. I am curious to know what issue is causing this. My cardiologist asked me to send some of my results which I did but he hasn’t answered in awhile. As I said I have had every test imaginable and I know it’s not serious I’m just interested in understanding test results rather than just having the doctor say you have pac’s or pvc’s or tachycardia.
